Figure 5. The effect of vector population reduction on the control of T. brucei using insecticide.

Figure 5

The relationship between the basic reproductive value, R 0, and the proportion of cattle among all non-human mammalian hosts in the situation where all cattle are treated with an insecticide that kills any fly attempting to feed off that animal. The dotted lines show the further change in R 0 in the circumstance that the imposed mortality results in a decline in the tsetse population.
